two coins and one six sided number cube are tossed together. What is the probability of getting two heads and a four?

Elis [28]

Answer:

The probability of getting two heads and a four is 1/24

Step-by-step explanation:

The probability of getting a head upon a single toss of a coin, assuming the coin is fair is 1/2.

The probability of getting two heads upon tossing two coins together will simply be the product of the individual probabilities;

P (HH) = 1/2 * 1/2 = 1/4

On the other hand, the probability of getting a four upon rolling a six sided number cube is;

1/6

This is because the number 4 occurs only once in a total possible of 6 numbers.

Therefore, the probability of getting two heads and a four;

P (HH4) = 1/2 * 1/2 * 1/6 = 1/24 since the three events are independent.

Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing th

hammer [34]

Answer:

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$

Step-by-step explanation:

Step 1:-

Given Suzan has three red marbles, two green ones, five white ones, and two purple ones.

Total marbles = 3R+2G+5W+2P = 12

The number of exhaustive cases that the five marbles drawn from 12 marbles

n(S) = $12C_{5} = 792 ways$

by using formula $n_{Cr_{} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-5)!5!}$ = 792

The number of favorable cases

She has drawn two red marbles from 3 red marbles, that is 3c₂ ways

she has drawn one marble drawn from 2 green marbles, that is 2c₁ ways

she has drawn one marble drawn from 5 white marbles, that is 5c₁ ways

she has drawn one marble drawn from 2 purple marbles, that is 2c₁ ways

The favorable cases are (n(E) = 3c₂ X 2c₁X5c₁X2c₁ = 60 ways

Required Probability = $\frac{n(E)}{n(S)}$

$Required probability = \frac{n(E)}{n(S)} = \frac{60}{792}$

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$
