Question

What is the probability of rolling a 1 with a number cube that has the numbers 1, 2, 3, 4, 5, and 6 and tossing heads with a coin?

A. 1/12
B. 1/8
C. 1/2
D. 2/3

Answer 1

A. 1/12

Probability of tossing dice= 1/6
Probability of tossing coin= 1/2
Find least common denominator and mutiply : 1/2*1/6= 1/12

Answer 2

probablity is (desired outcomes)/(total) possible outcomes so the dice 1 is desired and the total poassible outcomes is 6 since 6 numbers so probailty of rolling a 1 is 1/6 then flippin heads desired outcome=1 total possible=2 probabilty is 1/2 so we have 1/6 and 1/2 now we mulitply them 1/6 times 1/2=1/12 the answer is A
