Answer:

The probability that the 2nd Heads occurred at the 4th toss is 5.99%.

Step-by-step explanation:

Given that there were 4 Heads in the first 7 tosses, to find the probability that the 2nd Heads occurred at the 4th toss the following calculation must be performed:

7 - 4 = 3

4/7 x 3/7 x 3/7 x 4/7 = X

0.571 x 0.428 x 0.428 x 0.571 = X

0.0599 = X

Therefore, the probability that the 2nd Heads occurred at the 4th toss is 5.99%.

(4) 64 tiles, (5) $\mathrm{N}=\mathrm{s}^{2}$ , (6) $N^{2}=S^{4}$

Step-by-step explanation:

Given data: Side length of square tile = 1 ft

(4) Side length of square pool = 8 ft

$\text {Number of tiles} =\frac{\text { Area of square pool }}{\text { area of square tile }}$

$=\frac{8 \times 8}{1 \times 1}$

= 64

Hence 64 tiles needed for the border.

(5) Suppose number of square tiles be N and side of square tub is s ft.

So, N = $\frac{s \times s}{1 \times 1}$

$\Rightarrow N=s^{2}$

So, the expression is $\mathrm{N}=\mathrm{s}^{2}$ .

(6) The equivalent expression is $\mathrm{N}^{2}=\mathrm{S}^{4}$ .
