Answer:The right answer will be
0. 546875
Step-by-step explanation:
When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64
The number of ways of getting two heads are 6!/2!*4!=15.
The probability of getting two heads P(A) is 15/64 .
In the same way, the probability of getting three heads P( B) is 5/16.
Now, P(A)+P(B)= 0.546875
<span>Residents who are under 25 years and those above are mutually exclusive.
Let V = number of persons who take Vanilla under 25yrs and V' be the number of residents who are at least 25yrs who take Vanilla.
Okay, so P(V) = 40/150 and P(V') = 15/150
P(V or V') = 40/150 + 15/150 = 0.366</span>
