5/168

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome.

According to the question, if the bag contains 5 red raffle tickets, 7 blue raffle tickets and 2 green raffle tickets, the total number of ticket is given as:

5+7+2 = 14tickets

The total outcome = 14.

If Jackie selects a green ticket on her first two selections, the probability of selecting a green twice from the bag and replacing it will be 2/14×2/14 = 4/48.

Note that the total number of ticket remains complete each time she selects since the ticket was always REPLACED.

If Jackie picks a red on her third selection, the probability of picking a red will be 5/14.

The probability that she selects a green ticket on her first two selections and a red ticket on her third selection will then be:

= 4/48 × 5/14

= 1/12×5/14

= 5/168

5/686

Step-by-step explanation:

Red raffle tickets=5

Blue raffle tickets=7

Green raffle tickets= 2

Total raffle tickets=14

Three tickets were selected randomly with replacement

Probability of selecting Green tickets on her first two selections and red tickets on her third selection =propability of selecting Green raffle tickets twice and red raffle tickets once

=2/14×2/14×5/14

=1/7×1/7×5/14

=1/49×5/14

=5/686

Note: There are two green tickets and since it is selected with replacement, the total green tickets and the total raffle tickets doesn't change.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
