Shaun has five coins in his pocket. If he empties the coins onto a table, what is the probability that all five coins will land on heads? A. 1/32 B. 5/32 C. 1/10 D. 1/7

A. 1/32

Step-by-step explanation:

Ok, the probability for one of the coins to land on heads is 1/2 cause a coin have to sides and chance is 50% that it will land on either of its sides.

If you have 2 coins the probability will be 1/2 for the first coin to land on heads and 1/2 for the second one. The overall probability for 2 coins would be (1/2)*(1/2)=1/4. You could also see it is 1/4 because all of the possible combinations of 2 coins are 4 (HH, HT, TH, TT) and HH is one of four.

It's the same if you have 5 coins. The probability will be (1/2)*(1/2)*(1/2)*(1/2)*(1/2)=1/32 in other words is one of 32 possible combinations of 5 coins.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
