Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Probability that he jumps a hurdle = 
Total number of hurdles = 10
Probability that he knocks down = 
So, Probability (knocks down all hurdles ) is given by
Hence, Option 'a' is correct.
Just multiply man 2*4 2*3 1.5*4 and 1.5*3.
Answer:
The correct answer is 2.2.
Step-by-step explanation:
The following represents the probability distribution for the daily demand of microcomputers at a local store:
Demand Probability
f(0)= .1
f(1)= .2
f(2)= .3
f(3)= .2
f(4)= .2.
Expectation of a discrete probability function f of the random variable x is given by ∑ x × f(x).
Thus the expected value of demand is given by
0.1 × 0 + 0.2 × 1 + 0.3 × 2 + 0.2 × 3 + 0.2 × 4 = 2.2.
The expected daily demand is 2.2.
