Answer:

The correct answer is option B.

Step-by-step explanation:

The basic reasoning indicates that in roulette you can only get red or black in an instant (one time), then every time you turn the wheel, the probability of getting red or black is (0.5) 50% due to which they are mutually exclusive events.

Answer:

The correct answer is Option D. 20

Step-by-step explanation:

From the figure we get,

<RUS = 90° because RU ⊥ TS

<u>To find the value of x</u>

It is given that <RUS = 4x + 54

Therefore we can write,

4x + 54 = 90

4x = 90 - 54 = 36

x = 36/4 = 9

<u>To find RS</u>

It is given that,

RS = 3x - 7 = 3*9 -7 = 20

Therefore the correct option is Option D . 20
