hello

to solve this problem, we shall solve the first probability and then multiply it by the second probability

probability that the first number is 3 is 1/8

probability that the second number is 6 is 1/8

note: in this type of probability, each time the spinner goes around, the probability of picking a particular number is 1 over the total number of regions in the spinner

therefore, the probability of the first number to be 3 and the second number 6 is


P(e)=P(3)* P(6)=(1)/(8)*(1)/(8)=(1)/(64)

the answer to this question is option D
