2. What is the experimental probability of rolling a 4
boyakko [2]

Answer:

1. 40%

2. The theoretical probability is 3% greater than the experimental probability.

Step-by-step explanation:

We are informed that a number cube is rolled 20 times and the number 4 is rolled 8 times. The experimental probability of rolling a 4 is;

(the number of times a 4 was rolled)/(total number of rolls)

8/20 = 0.4

0.4*100 = 40%

The experimental probability of obtaining at least one tails, one or more tails, is represented in mathematical notation as;

P(HT or TH or TT)

The above events are mutually exclusive, thus;

P(HT or TH or TT) = P(HT) + P(TH) + P( TT)

                               = (22+34+16)/(28+22+34+16)  

                               = 0.72 = 72%

On the other hand, the theoretical probability of obtaining at least one tails,

P(HT or TH or TT) = 3/4

                              = 75%

This is because there is at least one tail in 3 out of 4 possible outcomes.

Therefore, it is true to say that the theoretical probability is 3% greater than the experimental probability.

I need help with this one pls!

Hi there!

\large\boxed{b = \frac{a}{ac - 1}}

We can begin by making each fraction have a common denominator:

If we make each have a common denominator of ab, we get:

\frac{b}{ab} + \frac{a}{ab} = c

Simplify:

\frac{a + b}{ab}  = c

Multiply both sides by ab:

a + b = cab

Move b to the opposite side:

a = cab - b

Factor out b:

a = b(ac - 1)

Divide by (ac - 1):

\frac{a}{ac - 1} = b
