If you mean to the power of 3 the answer should be 0.421875
Answer:
The required probability is 4/7.
Step-by-step explanation:
The sample space for the experiment is: { BB, BR, RB, RR }
The outcome of the event we require is: { BR, RB }
The probabilities for each outcome is given as:
BB: 3/7 x 2/6 = 1/7
BR: 3/7 x 4/6 = 2/7
RB: 4/7 x 3/6 = 2/7
RR: 4/7 x 3/6 = 2/7
Adding the probabilities we have:
{ BR, RB} = 2/7 + 2/7 = 4/7
That's it!

Answer:
The slope is 2/5 (0.4).
Step-by-step explanation:
The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:
m = (9 - 7)/(5 - 0)
Subtract 7 from 9 to get 2.
m = 2/(5 - 0)
Any number subtracted by 0 equals itself.
m = 2/5, or 0.4 is the final answer.
