Answer: There is probability that he will be asked a question in class during Week 7 is 64%.
Step-by-step explanation:
Since we have given that
Probability that question in class being asked during Week 1 = 1%
Probability that question in class being asked during Week 2 = 2%
Probability that question in class being asked during Week 3 = 4%
and so on.
So, we need to find the probability that question being asked in class during week 7.
Since it forms geometric series:
1%, 2%, 4%, ........
So, we need to find the 7 th term:
Hence, there is probability that he will be asked a question in class during Week 7 is 64%.
Answer:
Pr(of getting 1grape ball, 1 cherry ball and 1 lemon ball) =0.20832
Step-by-step explanation:
Let the grape falvored ball be represented by G,
Cherry flavored balls be C
Lemon flavored balls be L
the possible order of picks for getting 1grape ball, 1 cherry ball and 1lemon ball are; GCL or GLC or CGL or CLG or LGC or LCG
Pr(of getting 1grape ball, 1 cherry ball and 1 lemon ball)
= Pr(GCL) or Pr(GLC) or Pr(CGL) or Pr(CLG) or Pr(LGC) or Pr(LCG)
with replacement we have;
Probability =
=
= 0.03472 + 0.03472 +0.03472 + 0.03472 + 0.03472 + 0.03472
=0.20832
