Of the 64 people who answered yes to question 6 were male. of the 70 people that answered no to the question 8 or male. if one person is selected at random from the group what is the probability that the person answered yes or was male? 0.537 0.582 0.104 0.094

A. 0.537

Step-by-step explanation:

Number of people answering yes = 64

Number of people answering no = 70

Total number of people who answered = 64 + 70 = 134

Thus, the probability of answering yes = P(Y) = = 0.478

Further, out of 64 people answering yes, number of males = 6 and out of 70 people answering no, number of males = 8

We get, the probability of males answering yes = P(Y and M) = = 0.045

Since, total number of male = 6 + 8 = 14

Thus, the probability of males = P(M) = = 0.104

Now, as we have, P(Y or M) = P(Y) + P(M) - P(Y and M)

i.e. P(Y or M) = 0.478 + 0.104 - 0.045

i.e. P(Y or M) = 0.582 - 0.045

i.e. P(Y or M) = 0.537

Hence, the probability that the person answered yes or was a male is 0.537.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
