Deena and Jackson tossed two coins at the same time. In five tosses, Deena got heads on both coins three times. In

50 tosses, Jackson got heads on both coins 12 times. What does this illustrate about theoretical and experimental

probability that both tossed coins will be heads?

A- Experimental probability is not affected by sample size

B- Experimental probability approaches theoretical probability when the sample size is large.

C- Smaller groups give more accurate results.

D- Larger groups have greater chance for error

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
