Math Worksheets Coins

Question: Algebra 2 help pleaseeeeee?

These are some select problems that I’m not sure about out of a bunch that I get from the math from random worksheets I downloaded to teach myself Alg 2 over the summer. I numbered them for the convenience of answering. If anyone can solve and explain all of them it would be great, because I learn best from seeing it done… Thanks for all your help! I will award best answer asap to the most thorough answers!

1. We toss 4 coins at the same time. What’s the probability of the event “exactly 3 Heads appear”? (Give your answer as a fraction, not as a decimal.)

2. We perform the experiment “toss three coins” 1,000 times. How many times do you expect that the event “no heads” will occur?

Thankssss! <3

Answer: 1. 3/8

2. 3/6 ?
