Answer:
The probability that both the students selected are of the same gender is 0.25.
Step-by-step explanation:
Let <em>X</em> = number of students selected of the same gender.
The probability of selecting a student of a particular gender is,
P (X) = <em>p</em> = 0.50.
The number of students selected is, <em>n</em> = 2.
The random variable follows a Binomial distribution.
The probability of a binomial distribution is computed using the formula:

Compute the probability that both the students selected are of the same gender as follows:
P (Both boys) = P (Both girls) = P (X = 2)

Thus, the probability that both the students selected are of the same gender is 0.25.
Answer:
rearrange the formula A=lw and make the width the subject of the formula
therefore to find width, the formula is w=A/l
Assuming the radical between 6b and 7 to be +.
<span>6-4(6b + 7) >122
6 - 4*6b - 4*7 > 122
6 - 24b - 28 > 122
-24b > 122 + 28 - 6
-24b > 144 When you divide by a -ve number the inequality sign reverses
b < 144/-24
b < -6
