Answer:

1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.

Step-by-step explanation:

1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.

Consider the series.

Serga [27]

Put 1

$\\ \rm\Rrightarrow \left(\dfrac{3^{1+1}}{3(1)+1}\right)$

$\\ \rm\Rrightarrow 3^2/4=9/4=2.2$

Put 2

$\\ \rm\Rrightarrow \left(\dfrac{3^{2+1}}{3(2)+1}\right)=3^3/7=27/7=3.8$

R is

3.8/2.2=19/11

Its greater than 1 .

So diverge series.
