Answer:
choice 1) 2x + 40 = 180
Step-by-step explanation:
(x + 10) + (x + 30) = 180
2x+ 40 = 180
Flipping a coin is an independent event, meaning the probability of getting heads or tails does not depend on the previous flip. It's 1/2 or 0.5 chance every time.
So three coin flips would be = (0.5)*(0.5)*(0.5)
= 0.125
× 100%
= 12.5% chance
If you multiply everything by 6, you can get rid of all of the fractions and it’ll be much easier to solve!
