Answer:
<h3>#7</h3>
(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 <h3>#8</h3>
(a) <u>Sample space:</u>
1T, 1H, 2T, 2H, 3T, 3H, 4T, 4H Total 8 outcomes
(b)
(i) 1T, 3T
(ii) 1H, 4H
P(H and square) = 2/8 = 1/4 (iii) 1H, 2H, 3H, 4H
So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.
