If you spin the spinner 48 times, what is the best prediction possible for the number of times it will land on pink or green? times

Answers

answer: the best prediction is about once .
hope this helps you out & I’m not 100% sure if this is right so sorry if it’s wrong .

The best prediction possible for the number of times it will land on pink or green is 48 times, As the total probability is 1.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A spinner has 4 pink parts and 2 green parts.

The probability that it would land or pink or green is P(P) + P(G).

= (4/6) + (2/6).

= (4 + 2)/6.

= 6/6.

= 1.

Now, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory. Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.

Therefore, The best prediction possible for the number of times it will land on pink or green is,

= 48[P(P) + P(G)].

= 48(1).

= 48 times.
