The probability is 0.1785

The study of how likely certain events are to occur is known as probability. In its simplest form, it is concerned with the fall of a game's cards or the roll of a dice. However, probability is also essential to life and science as a whole. Probability is used, for example, in weather forecasting and figuring out how much your insurance premiums will cost.

Given probability of tail by spinning a coin is 65% = 0.65

p(t) = 0.65 and p(h) = 0.35

where h= head and t= tail

coin spins 4 time

p(t) for first time = 0.65

p(t) for second time = 0.65 x 0.65 =0.4225  

p(t) for third time = 0.65 x0.65 x 0.65 = 0.274

p(t) for fourth time = 0.65 x 0.65 x0.65 x 0.65 = 0.178

Hence probability that a student who spins 4 pennies will have them all land tails is 0.178

Answer:

Step-by-step explanation:

3x + 18 = 48

Bringing like terms on one side

3x = 48 - 18

3x = 30

x = 30/10

x = 3

Answer:

x = 10

Step-by-step explanation:

Subtract 18 from both sides.

3x=48-18

Simplify  48-18 to 30.

3x=30

Divide both sides by 3.

x= 30/3

Simplify  30/3\ to 10

x=10

x=10

Given:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

To find:

The probability of drawing a quarter, replacing it, and drawing another quarter.

Solution:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

Total number of coins = 8+5+1+7 = 21

Probability of getting a quarter is

[tex]P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}[/tex]

[tex]P(Quarter)=\dfrac{7}{21}[/tex]

[tex]P(Quarter)=\dfrac{1}{3}[/tex]

After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., [tex]P(Quarter)=\dfrac{1}{3}[/tex].

The probability of drawing a quarter, replacing it, and drawing another quarter is

[tex]P=\dfrac{1}{3}\times \dfrac{1}{3}[/tex]

[tex]P=\dfrac{1}{9}[/tex]

Therefore, the required probability is [tex]\dfrac{1}{9}[/tex].

Answer:

number 2 is c

number 1 is d?

Step-by-step explanation:

because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35  words 35m=w

for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer

Answer:

(For your second question.):

35w=m

Step-by-step explanation:

Why?

It states in the problem itself that miles types 35 words per minute.

"w" stands for words

'm' stands for minutes.

The constant rate relies on the clearest data after all. The equation itself is enough!

Remember: 1 min = 60 seconds.
