1/7 and 3/14......common denominator is 14
2/14 = 3/14
cross multiply
(14)(3) = (14)(2)
42 = 28...not correct...no, this does not form a proportion
little tip ** proportions are nothing but equivalent fractions and 1/7 does not equal 3/14...now if it would have been 1/7 and 2/14...then it would have been a proportion
Answer: 2.2532
Step-by-step explanation:
From the table attached :
Expected probability = sum of p(x) * x ; wher P-X) is the probability of x
E(p(x), x) = (0*0) + (1 * 0.06) *(2*0.1) + (3 * 0.16) * (4 *0.16)+ (5*0.26) * (6 *0.08) + (7 * 0.13) + (8 * 0.05)
Pp(x) * x) = 2.2532
Therefore, the expected value of the distribution is 2.2532
