Question

A spinner with 4 equal sections (red, blue, green, yellow) is spun 43 times. About how many times would you predict it lands on blue? Explain.

Answer 1

Answer:

11 times

Step-by-step explanation:

Sample space = {red, green, blue, yellow)

Probability of landing blue in a single spin ;

P(blue) = required outcome / Total possible outcomes

P(blue) = number of blue / sample space

P(blue) = 1/4

Number of spins = 43

Expected number of times it'll land on blue :

P(blue) * number of spins

1/4 * 43 = 10.75

About 11 times
