What is the probability of landing on blue?

Solutions

Expert Solution

Consider the spinner given in the text book. The spinner consists of seven colored sections and each section is labeled by a number.

The sample space for the given experiment is,

S= {B1, P2, G3, B4, R5, O6, Y7}

Hence, n(S) = 7

Assume that F represents the event of landing on blue. Then,

F{B1, B4}

Hence, n(F) = 2

Use the formula of probability of an event E,

P(E) = n(E)/n(S) ...... (1)

Using formula (1), the probability of landing on blue will be,

P(F) = n(F)/n(S)

= 2/7
