Answer:
15y / 8
Step-by-step explanation:
Multiplying by 2 to get the common denominator.
3y / 4 * 2 = 6y / 8
Combine like terms.
6y / 8 + 9y / 8
Final Answer:
15y / 8
Answer:
60
Step-by-step explanation:
The triangles are similar so corresponding angles will be congruent. We also know this because both angles have two lines marking they are congruent.
Answer:
Fractional probability of having 3 boys and 0 girls in a family for first 3 births is .
Step-by-step explanation:
Let A be the event of birth of a boy.
Let B be the event of birth of a girl.
Probability of birth of a boy, P(A)
Probability of birth of a girl, P(B)
We have to find the probability of birth of 3 boys i.e. event A occurring 3 times in a succession. It is independent events i.e. do not have any dependency on occurrence of any event.
So, Required probability can be calculated just by multiplying P(A) for 3 times.
i.e.
So, the probability of having 3 boys and 0 girls in the family is .
