Question:

If you spin the spinner 11 times, what is the best prediction possible for the number of times it will land on pink?

The spinner has

Blue = 4

Pink = 2

Black = 1

Yellow = 1

Answer:

P (pink) = 0.25

n = 3 times

Therefore, the best prediction possible for the number of times it will land on pink is 3 times.

Step-by-step explanation:

We know that probability is given by

P = Number of desired outcomes/Total number of outcomes

Where the total number of outcomes are

Total outcomes = Blue + Pink + Black + Yellow

Total outcomes = 4 + 2 + 1 + 1

Total outcomes = 8

And the number of desired outcomes are

Desired outcomes = Pink

Desired outcomes = 2

So the probability is

P (pink) = 2/8

P (pink) = 1/4

P (pink) = 0.25

The required number of times

n = 0.25*11

n = 2.75

Rounding off to nearest whole number

n = 3 times

Therefore, the best prediction possible for the number of times it will land on pink is 3 times.
