PLEASE HELP! A basket contains four apples and five peaches. Three times, you randomly select a piece of fruit, return it to the

Lana71 [14]

Answer:

100 / 729

Explanation:

The general formula to calculate the probability of each event is:

Probability = number of positive (desired) outcomes / number of total outcomes

Number of apples = 4

Number of peaches = 5

Number of fruits = 9

Since the three times you return the radomly selected fruit, and then mix it, the three times the probability is not affected by the previous selection; so, these are independent events, and you can calculate the probability of the joint event as the product of the probabilities of each individual event.

First time:

Probability of getting an apple = number of apples / number of fruits = 4 / 9

Second time:

Probability of getting a peach = number of peaches / number of fruits = 5 / 9

Third time:

Probability of getting a peach = number of peaches / number of fruits = 5 /9

Joint probability:

= (4/9) × (5/9) × (5/9) = (4 × 5 × 5) / (9 × 9 × 9) = 100 / 729

stepladder [879]

Step-by-step explanation:

${a}^{2} = {4}^{2} + {2}^{2} \\ {a}^{2} = 16 + 4 \\ {a}^{2} = 20 \\ a= \sqrt{20} \\ {x}^{2} = {( \sqrt{20} )}^{2} + {3}^{2} \\ {x}^{2} = 20 + 9 \\ {x}^{2} = 29 \\ x = 5.385$
