What is the probability of flipping two tails and rolling an even number

Two tails on two coins, 1/4 chance
An even number on a die 3/6 or if simplified, 1/2.

The other answer is correct if these are separate tasks.  However, if you need to flip two tails and roll an even as the question states you need to multiply the probabilities together.
It is 1/2 to flip a tail and we have that twice and 1/2 to roll an even and we have that once so the formula is

1/2 * 1/2* 1/2 = 1/8

The probability of doing all three things together is 1/8

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
