a computer programmer has a 35% chance of finding a bug in any given program. what is the probability that she finds a bug within the first three programs she examines?
a fair coin is flipped multiples times until it lands on heads. if the probability of landing on heads is 50%, what is the probability of first landing on heads on the fourth attempts?
1. i think is a or b
2. i think is a if not c
sorry if there wrong i tried but i hope it
(if both are wrong go ahead and report mine if you want)
up your but and around the corner
4x + y = −2 --> 4x = -y - 2
4x + 6y = 44
substitute 4x in the 2. equation.
(-y - 2) + 6y = 44
5y - 2 = 44
5y = 46
y = 9.2
4x = -9.2 - 2
4x = -11.2
x = -2.8
