Its’a D or B, sorry if I couldn’t help but it’s one of those
Answer:
either A or B, I'm leaning more towards B
Answer:
instrumentality
Explanation:
Instrumentality is a term that is used by Talcott parsons and Robert Bales to refer to an emphasis on tasks, a focus on more distant goals and concerns for he external relationship between one's family and other social institutions.
Instumentality is of the belief that successful performance will result in some outcomes. And the outcomes will be more technical and instrumental to a set of subjective probabilities.
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
