<u><em>ANSWERS ARE AT THE BOTTOM.</em></u>

To find the probability of 2 events happening in a row, we need to <u><em>multiply their probabilities.</em></u>

For example, if a friend bet: "If you roll a six on a dice and filp and coin and get heads, then I'll give you 500 bucks. However, if you don't roll a six and flip and coin and get heads in a row, then you have to give me 500 bucks."

You want to know the probability of you winning this bet.

So, we need to multiply the probability of rolling a six, and the probability of flipping a coin and landing heads.

This is 1/6 * 1/2

That is 1/12

You probably should't take this bet, because you only have a 1/12 chance of winning.

Lets go back to your problem. The jar contains 16 red marbles and 28 blue marbles. The probability of picking a red marble right now is 16/28, or 4/7. Assume we picked a red marble on our first try. Now, there are only 15 red marbles. The probability of picking a red marble right now is 15/28.

Probability of picking a red marble on your first try:  4/7

Probability of picking a red marble on your second try:  15/28

Now, we need to multiply the probabilities.

4/7 * 15/28

60/196

15/49

<u><em>ANSWER:</em></u>

<em>15/49</em>

Simplify (9 + 8 – 6)(4 – 5).
Temka [501]

The answer would be - 11.

Step-by-step explanation:

9 + 8 = 17

17 - 6 = 11.

4 - 5 = 4 + - 5 = - 1

11(- 1) = 11 × - 1 = - 11

Therefor, your answer would be - 11.

A man standing at point A walks 1 mile south, 3 miles east, 5 miles north, and 7 miles west to reach point B. The length of line
joja [24]

Answer: √32

Step-by-step explanation: so the displacement is north 4 and west 4 and it becomes a right triangle so the hypotenuse is the distance for segment AB

So Drawn out should like straight lines up,down,left,and right. So east is positive while west is negative same for North(+) and South(-)

I recommend sticking with 2 directions first. Starting with north and south right. First you go south 1 mile but then you go north 5miles in math terms

-1+5=4 or down one is one less than 5

Same for east and west. 3+-7 = -4

So we went positive 4 miles up and 4miles to the left

So (-4)^2+4^2= hypotenuse or AB segment in this case
