P(tail) = 1/2
P(even number) = 1/2

P(tail, tail, even) = (1/2) (1/2) (1/2) = 1/8

Answer: 1/8

each coin flip has a 1/2 probability of landing on tails
so 1/2 x 1/2 = 1/4 probability of getting 2 tails

a single die has 3 even numbers so you have a 3/6 = 1/2 probability of getting an even number

multiply both together for probability of 2 tails and an even number: 1/4 x 1/2 = 1/8 probability
