Question

A number wheel is divided into 15 equally-sized segments. Each segment is numbered 1 through 15. If Amelie s

wheel, what is the probability that the number will be a 4, 5, 6, or 7?
A. 33.3%
B. 26.7%
20%
D. 13.3%
E. 6.7%

Answer 1

B) P(E) = 26.7%

Explanation:

Probability of an event E =
`\frac{\textrm{Favorable Outcomes}}{\textrm{Total Outcomes}}`

Now, here let E be the event of getting a number 4,5,6 or7.

Total Outcomes = 15

So, P(E) = favorable Outcomes / Total Outcomes =
`(4)/(15)`

⇒ P(E)= 0.2666

or P(E) 0.266 x 100 = 26.7 %

So, B is the correct option.
