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.
