Answer:

(a)

<u>Sample space:</u>

1*1, 1*2, 1*3, 1*4,
2*1, 2*2, 2*3, 2*4,
3*1, 3*2, 3*3, 3*4,
4*1, 4*2, 4*3, 4*4

Total 16 outcomes

(b)

(i) P(even) = 12/16 = 3/4
(ii) P(3x) = 7/16
(iii) P(perfect square) = 4/16 = 1/4

(a) <u>Sample space:</u>

1T, 1H, 2T, 2H, 3T, 3H, 4T, 4H

Total 8 outcomes

(b)

(i) 1T, 3T

P(T and odd) = 2/8 = 1/4

(ii) 1H, 4H

P(H and square) = 2/8 = 1/4

(iii) 1H, 2H, 3H, 4H

P(H) = 4/8 = 1/2

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

$(\frac{2}{3}s + \frac{5}{6}s) = 21$
$(\frac{4}{6}s + \frac{5}{6}s) = 21$
$\frac{9}{6}s = 21$
$\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
$s = \frac{42}{3}$
$s = 14$
