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 = $\frac{15}{182} =0.0824$

What is the value of E?

kozerog [31]

Hello!

∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:

∠E + 119 = 180

Now subtract 119 from both sides of the equation:

∠E = 61

We have now proven that ∠E is equal to 61 degrees.

I hope this helps!
