Answer:
1/6
Step-by-step explanation:
Probability is a chance of an event taking place.
Probability = (favorable outcome)/(total outcome)
There are 3 even sides in a dice.
P(even) = 3/6 = 1/2
There are 2 numbers that are greater than 4 in a dice.
P(x>4) = 2/6 = 1/3
P(even and x>4) = 1/2 × 1/3 = 1/6
If line x is parallel to line z in that case
angle 16 will be equal to the angle 9 which is 7y degrees
Let A1 = The land has oil
A2 = Land has no oil
B1 = Test Predicted that land has oil
B2 =Test Predicted that land has no oil
Required probability = P(A1/B2)
A1 and A2 are mutually exclusive and exhaustive. Hence we can use Baye theorem
P(A1/B2) = P(A1B2)/P(B2) =


Answer:
26
Step-by-step explanation:
Given that :
2 out of every 5 people buys vanilla ice cream;
If Total number of ice cream sold in a day = 65 ; how many will be vanilla ;
Probability of purchasing vanilla ; p(vanilla) = 2/5 = 0.4
Hence, expected number who bought vanilla :
p(vanilla) * total number of icecream sold
0.4 * 65 = 26
Hence, about 26 of the 65 icecream sold are vanilla flavor.
