Answer:
3/8 and 3/5
Step-by-step explanation:
Given that a family has three children. Using b to stand for a boy and g for girl give the following we can write sample space for a family having three children as
(bbb, bbg, bgg, bgb, gbb, gbg, ggb, ggg)
E - exactly two boys
Sample space count = 8
Exactly two boys count = 3
a) p(E) =
b) odds for E is probability/1-probability
=
Use BEDMAS the order of operations and solve the Brackets first.
Answer:
2 2/35 hours
Step-by-step explanation:
In 1 hour, the total amount of the house that is painted is ...
1/8 + 1/4 + 1/9 = 35/72 . . . of a house
We need to multiply the time (1 hour) by 72/35 to find the number of hours required for one entire house:
72/35(1 h) = 2 2/35 h
It would take them 2 2/35 hours to paint the house working together.
Answer:
