Answer:

about .63 or 17/27

Step-by-step explanation:

I know the probability is about .63 because I found the probability of not choosing a blue marble, which is the same as finding the probability of choosing a red, green or yellow marble. There are 4 red marbles, seven green marbles and 6 yellow marbles. There are 10 blue marbles. I knew there was 27 marbles in all, so I found the probability of choosing a red, yellow or green marble.

4+7+6

_____ = 17/27 ~ 0.62962962963

27

In conclusion, the probability of the event of not choosing a blue marble is about .63 or 17/27.

Answer:

17/27

Step-by-step explanation:

Since there are 10 blue marbles, and 27 total marbles, the probability of not choosing a blue marble is 17/27 because you subtract the amount of blue marbles (10) from the amount of total marbles (27).

The trick to solving problems with mixed units is to convert all of them into one unit or another, so:

There are 12 inches in a foot, so 72 inches = 6 feet.
To find the perimeter of a polygon, sum its sides.
Perimeter = 2 + 5 + 6 = 13 feet.

To find the area of a right triangle (which I assume the one in the picture is), we can use the following equation: A = 0.5 * base * height
There are 3 feet to one yard, so 6 feet = 2 yards.
Area = 0.5 * 2 * 1 = 1 yard^2

Luna entered a raffle for a new pair of running shoes. She purchased 20 tickets and was told that she had a 20% chance of winnin
xenn [34]

Answer:

<h3>100 tickets</h3>

Step-by-step explanation:

Probability of winning = amount of tickets purchased/Total number of tickets

20% = 20/total number of tickets

20/100 = 20/total number of tickets

cross multiply

20 * total number of tickets = 20 * 100

20 *  total number of tickets = 100

total number of tickets sold = 100 tickets
