The integer that represents her deposit would be positive 75 (aka just 75)

The integer that describes the opposite of her transaction (a withdraw) would be -75

The opposite of her transaction would also be -75

Hope this helps

In this case, Ainsley is <em>adding </em>money to her savings, so the $75 deposit could be represented as the <em>positive </em>integer 75.

The opposite, of course, would be if Ainsley <em>withdrew </em>that money from her savings. In that case, we'd be subtracting money from the account, so we could use the <em>negative </em>integer -75 to represent that scenario.

The chance of selecting 10 men is unlikely in a random selection

<h3>The probability that the jury is made of 2 men</h3>

The given parameters are:

Men = 17
Women = 15
Total = 32

The total number of selections is:

$Total = ^{32}C_{10}$

Evaluate

Total = 64512240

If 2 men are selected, then 8 women would be selected.

So, the number of ways is:

$Ways = ^{17}C_2 * ^{15}C_8$

Evaluate

Ways = 136 * 6435

Ways = 875160

The required probability is:

P = 875160/64512240

P = 0.0136

Hence, the probability that the jury is made of 2 men is 0.0136

<h3>The probability that half the jury are men</h3>

If 5 men are selected, then 5 women would be selected.

So, the number of ways is:

$Ways = ^{17}C_5 * ^{15}C_5$

Evaluate

Ways = 6188 * 792

Ways = 4900896

The required probability is:

P = 4900896/64512240

P = 0.0760

Hence, the probability that the jury is made of half men and women is 0.0760

<h3>The probability that at least two women are selected</h3>

To do this, we make use of the complement rule:

P = 1 - P(Not up to 2 is selected)

When 0 women are selected, then 10 men are selected and when 1 woman is selected, then 9 men are selected

So, the number of ways is:

$Ways = ^{17}C_{10} * ^{15}C_0 + ^{17}C_{9} * ^{15}C_1$

Evaluate

Ways = 19448 * 1 + 24310 * 15

Ways = 384098

The probability P(Not up to 2 is selected) is:

P = 0.0060

The required probability is:

P = 1 - 0.0060

P = 0.9940

Hence, the probability that the jury is made of at least two women is 0.9940

<h3>The probability that at 10 men are selected</h3>

When 10 men are selected, then 0 women are selected

So, the number of ways is:

$Ways = ^{17}C_{10} * ^{15}C_0$

Evaluate

Ways = 19448 * 1

Ways = 19448

The probability is:

P = 19448/64512240

P = 0.0003

Hence, the probability that the jury is made of 10 men is 0.0003

The selection above can lead to suspicion because the chance of selecting 10 men is unlikely in a random selection
