A golfer's bag contains 24 golf balls, 18 of which are ProFlight brand and the other 6 are DistMax brand. Find the probability t

Answer:

1. Assuming with replacement, the probability is 7.91%; or

2. Assuming without replacement, the probability is 8.64%

Step-by-step explanation:

Total number of golf balls = 24

Let Pr denotes probability, P denotes ProFlights, D denotes DistMax.

The probability of selecting 5 balls can be with or without replacement. Since the question is silent on this, the answers to the methods are provided as follows:

1. Assuming with replacement

Pr(4 P and 1 D) = (18/24) × (18/24) × (18/24) × (18/24) × (6/24)

= 0.75 × 0.75 × 0.75 × 0.75 × 0.25

= 0.0791 = 7.91%

2. Assuming without replacement

Here, we assume that 4 ProFlights are selected first before 1 DistMax is selected, and the probability is as follows:

Pr(4 P and 1 D) = (18/24) × (17/23) × (16/22) × (15/21) × (6/20)

= 0.7500 × 0.7391 × 0.7273 × 0.7143 × 0.3000

= 0.0864 = 8.64%

Therefore, the probability that he reaches in his bag and randomly selects 5 golf balls and 4 of them are ProFlights and the other 1 is DistMax is 7.91% assuming with replacement or 8.64% assuming without replacement.

A/b=c for b<br> please explain this is sorta confusing :'(

PtichkaEL [24]

If you want to solve $\dfrac{a}{b} = c$ for $b$ , start by getting rid of the fraction.

Multiply both sides of the equation by $b$ .

$b\cdot \dfrac{a}{b} = b\cdot c$

This will get rid of the fraction on the left and give you

$a = b\cdot c$

Now this is a regular old equation without fractions. To get $b$ by itself, you need to divide away $c$ from both sides of the equation.

Can you finish it from there?

Answer:

The ratio of Trucks to Cars is

$3: 14$

The ratio of Hot Dogs to Hamburgers is

$3 : 5$

Step-by-step explanation:

There are 42 cars and 9 trucks, and since they asked to write the ratio of trucks to cars, we write it as they asked. Therefore the ratio would be

$9 : 42 \\ \\ \frac{9}{3} : \frac{42}{3} \\ \\ = 3 : 14$

There are 24 hotdogs and 40 hamburgers, since they asked us to write the ratio of hotdogs to hamburgers we are going to write it as it was said. Therefore the ratio is

$24 : 40 \\ \\ \frac{24}{8} : \frac{40}{8} \\ \\ = 3 : 5$
