First, we need to figure out the probability of landing on white one time. The probability of landing on black is 1/2, and the probability of landing on red is 1/3. If we add these probabilities together we get:
So if there is a 5/6 chance of NOT landing on white, then there must be a 1/6 chance of landing on white.
To find the probability of landing on white 4 times, multiply 1/6 to itself 4 times.
The answer is D.
Answer:
20
Step-by-step explanation:
Answer:
2 y + x = 5 , 5 x − y = 3
Step-by-step explanation:
suppose x represents the smaller number and y represent the larger number.
Then
• The statement: “Twice a number added to a smaller number is 5”
<u><em>means</em></u> 2 y + x = 5
On the other hand,
•• The statement: “The difference of 5 times the smaller number and the larger number is 3”
<u><em>means</em></u> 5 x − y = 3
3/4 + 1/2
LCD=4
3/4 + 2/4
5/4 = 1 and 1/4
or 1.25 if decimal is required.
