Rolando tossed a coin 4 times.

which of the following is a list of all the possible outcomes with 2 or 3 heads?

2 ehads 1 tail 2 heads 2 tails  3 heads 1 tail

The answer might be 2 out of 3. I don't know... sorry!

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
