Answer:

d

Step-by-step explanation:

ur welcome plz mark brainliest

2/5 t is the probability that the balloon will be either red or blue.

Thus option A is correct.

The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.

The probability of the event will be taken as

The fact that the data of red and blue will have a chance of occurring in the event

The first draw chance would be 20/100 = 1/5

The second draw would be 20/100 = 1/5

P = 20 / 100 + 20 / 100

P = 1/5 + 1/5

P = 2/5

Therefore, option D is the correct option.
