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)

How do I simplify this?
Anastasy [175]
3/4 + 1 = 1.75 which is equivalent to 7/4
1- 3/4 = 0.25 which is equivalent to 1/4
the problem now looks like 7/4 / 1/4
you cancel out both 4
this problem simplified looks like 7/1
which is equivalent to 7 if you divide

Help me on this please

Answer:

x = 3.5

Step-by-step explanation:

Triangle to the right:

4^2 + x^2 = 8^2

16 + x^2 = 64

y^2 = 48

Triangle to the left:

x^2 + 6^2 = 48

x^2 + 36 = 48

x^2 = 12

x = sqrt(12)

x = 3.5
