Answer:
Probability of having at least 4 Girls
= 0.6875
Step-by-step explanation:
Probability of having at least 4 Girls is 1-probability of having exactly 3 girls
Total number of children= 5 = N
Probability of having a girl p = 0.5
Probability of not having a girl q= 0.5
X= 3
Probability of at least 4 girls is given by
Probability= NCX(p)^x(q)^(N-x)
Probability = 5C3(0.5)^3(0.5)^(5-3)
Probability = 5C3(0.5)^3(0.5)^2
Probability= 5!/3!2!(0.5)^3(0.5)^2
Probability= 10(0.125)(0.25)
Probability= 0.3125
Probability of having at least 4 Girls
= 1- 0.3125
= 0.6875
Hello,
Rational numbers are numbers that can be represented by fractions that consist of integers.
In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is =

= 9, which can be represented by 9/1, so it is also a rational number.
A and D are incorrect as they cannot be represented by fractions that consist of integers.
The answers are B and C.
Hope this helps!
