Jean bought a bag of candy that contained red candies, green candies, and brown candies. Some candies are marked with a smile and others are not marked. The probabilities are displayed in the table below:

Red Green Brown
Smile 0.10 0.30 0.10
No smile 0.20 0.15 0.15

If a random candy is chosen from this bag, what is the probability that the candy was red or had no smile?

Answer 8

@mangorox @OOOPS

Answer 9

whoops its
0.60

0.20

0.30

0.50

Answer 10

To make a decimal into a percent, move the decimal dot two places to the right. So, to probability to choose a red candy would be:
\[0.10 + 0.20 = 0.30 \approx 30 percent\]

30% red candy to be drawn out of the bag is the probaability

Answer 11

okay i get it i think

Answer 12

For candy to have no smile:
\[0.20 + 0.15 + 0.15 = 0.50 \approx. 50percent\]

50% is the probability a candy with no smile will be drawn

Answer 13

*50percent

Answer 14

wait so what is the answer

Answer 15

if its both 30% and 50%

Answer 16

weird ill put 30
