Hi Stacey,
There is a little bit mistake in one of the Navigator's specific problem of Official Guide 2017 edition.
Problem solving question# 221,
the correct equation should be:
P (Zelda does NOT solves the problem)=1-P(Zelda solves the problem)
--> P (Zelda does NOT solves the problem)=1-(5/8)
But, it has been written mistakenly the following:
P (Zelda does NOT solve the problem)=1-P(Zelda does NOT solve the problem).
I think it should be corrected if I'm not wrong!
also, in OG 2017 edition, PS#200, page#179
Quoted the line from Navigator (last line of the solution)
""Note that if we have mistakenly thought 143 was a prime, we should have identified only two unique primes between 1 and 100?''''
My Question: Should not it be three primes between 1 and 100?
Thank you Stacey...
