Any nonzero integer divided by 0 equals 0. True or false? Justify your answer.

1 answer:

6 0

It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.

Let the event $A=\{ Sophomore \}, B=\{ Boy \}$

The the probability of the events

$P(A \cap B)=\frac{5}{12+18} =\frac{1}{6}$

$P( B)=\frac{12}{12+18} =\frac{2}{5}$

The conditional probability

$P(Sophomore|Boy)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/6}{2/5} =\frac{5}{12}$

A casino features a game in which a weighted coin is tossed several times. The table shows the probability of each payout amount

kkurt [141]

Answer:

The expected payout of the game is $230.46.

Step-by-step explanation:

The given table is

Payout Amount : $160 $4400 $145000

Probability : 0.146 0.024 0.0007

We need to find the expected payout of the game.

The formula for expected payout is

$\text{Expected payout}=\sum n_iP(x_i)$

where, n is amount and P(x) is probability of that event. The value of n is negative for loss.

Using the above formula we get

$\text{Expected payout}=160\times 0.146+4400\times 0.024+145000\times 0.0007$

$\text{Expected payout}=23.36+105.6+101.5$

$\text{Expected payout}=230.46$

Therefore the expected payout of the game is $230.46.
