Distribution 73724

The distribution of the random variable X is given in the following table. Calculate P[X is odd], E[X] and P[1<X≤6]

Probability distribution table:
xi 1 2 3 4 5 6 7 8 9
pi 0.30 0.12 0.18 0.10 0.07 0.07 0.06 0.05 0.05


Correct answer:

p1 =  0.66
E =  3.52
p2 =  0.54

Step-by-step explanation:

p1=0.30+0.18+0.07+0.06+0.05=0.66
E=1 0.30+2 0.12+3 0.18+4 0.10+5 0.07+6 0.07+7 0.06+8 0.05+9 0.05=3.52
p2=0.12+0.18+0.10+0.07+0.07=0.54
