A=2(wl+hl+hw)=2·(2·6+24·6+24·2)= 408cm²
She must fill it 4 times as 4/8 is equal to 1/2
Answer:
Step-by-step explanation:
(7*11)-(22/7*2^2)
77-(22/7*4)
77-88/7
77-12.57
64.43
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
