A bag contains 10 red 6 green 12 orange and 8 purple candy's without looking Ann pulls one piece of candy out of the bag what is

Alex73 [517]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

GIVEN: A bag contains $10$ red $6$ green $12$ orange and $8$ purple candies, without looking Ann pulls one piece of candy out of the bag.

TO FIND: what is the probability that she pulls out a purple piece of candy.

SOLUTION:

Total number of candies in the bag $=36$

Total number of purple candies in the bag $=6$

Now,

Probability that Ann pulls out a purple piece of candy

$=\frac{\text{number of purple candies}}{\text{total candies in bag}}$

putting values,

$=\frac{6}{36}$

$=\frac{1}{6}$

Hence, the probability that she pulls out a purple piece of candy is $\frac{1}{6}$

Alfred collects black and brown socks but loses a lot of them. If 60% of all his socks are brown, 20% of his brown socks are in

Ipatiy [6.2K]

Answer:

Alfred has 250 socks in his collection.

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Based on the information given to us we can see that out of All his Brown socks he has 20% in the wash and the rest are in his drawer. Meaning 80% of the Brown socks are in his drawer. So we first need to find how many Brown socks are in the wash. We can solve this using the Rule of Three property as shown in the picture below.

120 drawer ⇒ 80%

x wash ⇒ 20%

$\frac{120*20}{80} = 30$

Now that we have the amount of Brown socks in the washer we can add that to the amount in the drawer to find the total amount of Brown socks.

$Br = 120+30\\Br = 150$

So we now know that there are a total of 150 Brown socks. Since the question states that the Brown socks are 60% of the total we can use the Rule of Three to find the total.

150 Brown ⇒ 60%

T Total ⇒ 100%

$\frac{150*100}{60} = T$
