Answer:
P( sum is prime )= 73/216
Step-by-step explanation:
The minimum value of the sum will be 3 and maximum value will be 18. So the prime numbers in this range are 3 , 5, 7, 11, 13, 17.
P(sum=3)=1/216, P(sum=5)=6/216, P(sum=7)=15/216, P(sum=11)=27/216, P(sum=13)=21/216, P(sum=17)=3/216.
The final probability will be sum of the above given probabilities.
Hence P( sum is prime )= 73/216

Answer:
The probability that in his next 5 back flips Daniel will land more than 3 of them is:
27%
Step-by-step explanation:
The outcomes that represent that he landed in his back flip more than 3 times are:
43113 43323 14221 11123 35133 15231
So, out of the total 22 trials the number of trials he will land more than 3 of them is:
6.
Let P denotes the probability of an event.
Hence,
P(He will land more than 3 times)=Number of trials in which he landed more than three times/Total number of trials.
P( He will land more than 3 times)=6/22
Hence, the percent probability is calculated as:
Hence, the probability that in his next 5 back flips Daniel will land more than 3 of them is:
27%
