If you flipped a penny and a nickel, and rolled a die, what is the probability of:
a. getting at least one head on the coins and a 6 on the die?
b. getting a head on both coins and a 4 on the die ?
c. getting a head on both coins and a 3 or a 5 on the die?
d. getting a head on both coins with anything on the die?
I THINK these answers are correct, if this is for a major grade, ask somebody and compare my answers to theirs.
Another person had the exact same answers as you. This is for a major grade! Thank You!!
. P(at least one head) is the same as 1 - P(no heads). Now, P(no heads) = 1/2 * 1/2 = 1/4 so P(at least one head) = 3/4. P(6) = 1/6. The total is 3/4 * 1/6 = 1/8.
actually for part a is it possible the answer could be 1/8?
Yes, the answer to (a) is 3/4 x 1/6 = 1/8
3/4 is the probability of getting at least one head in two coin tosses.
