You wanna has 240 in her savings account she deposit 20 each week matt has 600 in his savings account and with just 40 each week how many weeks will it take until they have the same amount of money

is there a question here?

step-by-step explanation:

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
