Question:

A pointer is spun once on a circular spinner (Fig. 3). The probability assigned to the pointer landing on a given integer (from 1 to 6) is the ratio of the area of the corresponding circular sector to the area of the whole circle, as given in the table:

ei P(ei) .1 2 .2 3 .1 + .1 5 .3 6 .2 S = { 1, 2, 3, 4, 5,6}

(A) What is the probability of the pointer landing on a prime number?

(B) What is the probability of the pointer landing on a prime number, given that it landed on an odd number?
