There are 4 red and 3 blue balls in a basket. The probability of getting a blue ball is
a. 3/7
b. 4/7
C. 7/7

Step-by-step explanation:

We want Blue balls & total number of balls is 7

Therefore,

probability \: of \: getting \: blue \: ball \: is \: \frac{3}{7}

3/7

So,

first is your answer

a) 3/7

Step-by-step explanation:

Probability of getting an outcome = Desired Outcomes/Total Number Of Outcomes

Here,

Desired Outcome = 3 (as there are 3 blue balls in bag)

Total Outcomes = 7 (Red Balls + Blue Balls; 4+3 = 7)

Therefore,

Answer = 3/7

b.) divide by -5.

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
