Drug addicted people have a compulsive desire and are unable to give up drugs willingly. Treatment is necessary to end this compulsive behavior.
Answer:
a= 1/4
b=15/16
Explanation:
There are no sequences or anything that can differ the 4 children, so the order in this probability is not important. Let's say chance the chance for a girl is A and chance for a boy is B, then
P(A)= 0.5 = 50%
P(B)= 1-0.5= 50%
(a) at least 3 girls
At least 3 girls mean you need to have 3 girls or more. The events that can fulfill at least 3 girls out of 4 children are
1. 3 girls and 1 boy
2. 4 girls and 0 boy
We can find the probability by adding these 2 events. The calculation will be:
P(3A1B) + P(4A0B)
= 3C1 * A^3 * B^1 + 4C0 * A^4 * B^0
P(3A1B) + P(4A0B)
= 3 * 0.5^3 * 0.5^1 + 1 * 0.5^4 * 0.5^0
P(3A1B) + P(4A0B)
= 3/16 + 1/16= 4/16 = 1/4
(b) at most 3 girls
At most 3 girls mean that less or equal to 3 girls. There are only 4 children, so the only event that did not fulfill the condition is 4 girls and 0 boy. It is easier to find the probability for 4 girls and 0 boy then calculate the negation, it will be:
P(4A0B)= 4C0 * A^4 * B^0=
P(4A0B)= 1 * 0.5^4 * 0.5^0=
P(4A0B)= 1/16
The probability will be ~P(4A0B)= 1- 1/16= 15/16
