Aquarter, a nickel, and a penny are flipped. find the probability of each of the following: -
a)the penny and nickel shows head
b)all these coins land the same way

The probability of an event is the measure of the chance that the event will occur as a result of an experiment. The probability of an event A is the number of ways event A can occur divided by the total number of possible outcomes.
a.) since each coin has 50% chance to have heads
(1/2) x  (1/2) = 1/4 probability The penny and nickel shows head

b.) All these coins land the same way
(1/2) x  (1/2) x  (1/2) = 1/8
