Consider the system of equatiosn , y=2x+2, y=6x+2 ,Which statements are true

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.

pats age should be less than 10 , therefore the greatest age (in integer)that pat can be is 9 years
