A jar of 70 candies has the following colors: 28 orange, 7 white, 14 brown, and 21 yellow.

What is the probability of randomly drawing a white or a brown candy?

The total number of candies in the jar is 70.

The number of white candies is 7 and the number of brown candies is 14.
To find the probability of drawing a white or a brown candy, we need to add the individual probabilities of these events occurring.

The probability of drawing a white candy is given by:
Number of white candies / Total number of candies = 7/70 = 1/10.

The probability of drawing a brown candy is given by:
Number of brown candies / Total number of candies = 14/70 = 1/5.

To find the probability of drawing a white or a brown candy, we add the two probabilities:
1/10 + 1/5 = 1/10 + 2/10 = 3/10.

Therefore, the probability of randomly drawing a white or a brown candy is 3/10.

To find the probability of randomly drawing a white or a brown candy, we need to determine the number of white and brown candies and divide it by the total number of candies.

Number of white candies = 7
Number of brown candies = 14
Total number of candies = 70

So, the probability can be calculated as follows:

Probability = (Number of white candies + Number of brown candies) / Total number of candies

Probability = (7 + 14) / 70

Probability = 21 / 70

Probability = 3 / 10

Therefore, the probability of randomly drawing a white or a brown candy is 3/10.
