Answer:
B.
Step-by-step explanation:
Total coins = 11 ( 3 + 4 + 4 = 11).
The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).
The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).
The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).
The probability of picking all three in that order = 3/11 x 2/5 x 4/9 = 8/165

Answer:
Step-by-step explanation:
Q no 4 :
4, 8
1, 5
3, 7
2, 6
Q no 5:
(a)
10x + 1 = 12x - 5
1+5= 12x - 10x
2x = 6
x = 6/2
x = 3
(b)
11x - 15 + 5x - 13 = 180 (angles on a straight line)
11x + 5x - 15 - 13 =180
16x - 27 = 180
16x = 180 + 27
16x = 207
x = 207 / 16
x = 12.9375
