Don't know if it's right however it is supposed to be solved like this i guess... There must be a mathematical error if the answer, you say, is 710

Given that, Sum of First and Fourth term is 70 and sum of Second and Third term is 60, so there's no way the sum to infinity be 10 or 7.
From the answer i posted,
r = 2/3 or 3/2
When r = 2/3,
a = 54
T1 = 54
T4 = 16
Hence T1 + T4 = 70
Again, When r = 3/2
T1 = 16
T4 = 54
Hence T1 + T4 = 70

It means P(-1 < x < 1) given X ~ N(0,1)
This would give probability within 1 standard deviation of the mean. Then use Binomial model to find the probability for more than 7 phone calls.

The box says that it follows Cambridge rules, it also lists everything that Cambridge doesn't allow in a calculator and says that this calculator doesn't have any of these, so I just wanted to do a double check. If anyone would specifically tell about 991EX, I will appreciate it! Thanks!
