Probability 2386

We throw a die seven times. What is the probability that:
a) the first, second, and third times fall six and not in all the others,
b) 5 does not fall four times in a row, and yes, in the last 3 hours?

Final Answer:

a =  0.2233 %
b =  0.2233 %

Step-by-step explanation:

p=610.1667 q=1p=10.1667=650.8333  a=100 p3 q4=100 0.16673 0.83334=0.2233%
b=100 q4 p3=100 0.83334 0.16673=0.2233%
