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?

A1/12
B1/8
C1/2
D2/3

Verified Answer :

A1/12

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

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
