Answer: 7/19
Step-by-step explanation:
Given that:
Probability of drawing 2 white cards without replacement = 14 / 95
Probability of drawing one white card = 2/5
Probability of drawing a second white card Given the first card is white will be :
P(2 white cards without replacement) = p(one white card) * p(second white card)
14 /95 = 2/5 * p
P = 14/95 ÷ 2/5
P= 14/95 * 5/2
P = 70 / 190
P = 7/ 19
Answer:
3
Step-by-step explanation:
15-2x=3x
or,3x+2x=15
or,5x=15
or,x=15/5
Therefore, x=3.
K=9S/2, total savings is S+9S/2=11S/2. So 9S/2÷11S/2=9/11. (a) The ratio is 9:11.
(b) Kieran’s savings are 9/11 of the total savings.
(c) Simon’s savings are S÷11S/2=2/11 of total savings (or simply subtract 9/11 from 1).
(d) K-S=28, 9/11-2/11=7/11 of the total savings, so 7/11 of the total savings is $28 and total savings is 11/7×28=$44.
CHECK
Kieran has 9/11 of $44 which is $36 and Simon has $8. 36/8=9/2 so the ratio is correct.
Simon has $28 less than Kieran and 36-8=28, which is correct.
I believe the answer is C, but I am not 100% sure. Though, I hope this helps.
