Answer:

Step-by-step explanation:
We have the cone and the half-sphere.
The formula of a volume of a cone:

r - radius
H - height
We have r = 7cm and H = (22-7)cm=15cm. Substitute:

The formula of a volume of a sphere:

R - radius
Therefore the formula of a volume of a half-sphere:

We have R = 7cm. Substitute:

The volume of the given shape:

Substitute:

Step-by-step explanation:
Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6
Even= 2,4,6
Odd = 1 ,3 , 5
Probability of getting even =
Probability of getting odd = 
4 dices are rolled together
a)P(3 even and 1 odd numbers)
P(3 even and 1 odd numbers)=
P(3 even and 1 odd numbers)=
b)P(2 even and 2 odd numbers)
P(2 even and 2 odd numbers)=
P(3 even and 1 odd numbers)=
=0.375
