Probability of having at least 1 boy = 1 - the probability of having ALL girls.
P(5 girls) = (1/2)⁵ = 1/32
P(At least 1 boy) = 1 - 1/32 = 31/32
Answer: 31/32
Answer:
6 less a number y can be represented by the expression 6 - y
Here's the slope form; (y2- y1) / (x2 - x1)
All you have to do now is just plug in the number into the formula.
(6 - -4) / (6 - 1) = 10/5
Then divide, and the answer is D. 2.
Answer:
a² + b²
Step-by-step explanation:
