Answer:
y = 4
Step-by-step explanation:
-1y = -4
Divide both sides by -1 to get y by itself.
-1/-1 = -4/-1
y = 4
It's positive because there are two negatives, which mean they cancel out.

Probability of at-least 2 girls = Probability of 2 girls + Probability of 3 girls + Probability of 4 girls + Probability of 5 girls = 1 - (Probability of no girl + probability of 1 girl)
We know:
<span>probability when no girl = 5C0 * (1/2)^0 *(1/2)^5 = 0.03125
probability when one girl = 5C1 * (1/2)^1 *(1/2)^4 = </span>0.15625<span>
probability when at least 2 girls = 1-(0.03125+</span>0.15625<span>)
= 0.8125(approx)
</span>
