Question

You toss tails and roll an even number ( when you toss a coin and roll a number cube)

Find the probability.
I thought It was 1/3 but I think that is wrong.

Answer 1

prob(tail and even) = (1/2)(3/6) = (1/2)(1/2) = 1/4


proof:
cases:
t1 t2 t3 t4 t5 t6
h1 h2 h3 h4 h5 h6 ---- 12 of those

tail and even:
t2 t4 t6 ----- 3 of those

prob = 3/12 = 1/4


explain why you thought it was 1/3.
