Visa cost = £2300
7% charge of visa price = (0.07 * £2300) = £161

Amount to be saved per month = £2461 / 12 = £205.08333
= £210 (nearest £10)
Answer:
0.643
Step-by-step explanation:
Let, s = play a sport
c = participate in a club
P(s) = 0.14
P(s n c) = 0.09
probability that a student participates in
a club given that they also play a sport = P(c | s)
P(c | s) = P(c n s) / P(s)
P(c | s) = 0.09 / 0.14
P(c | s) = 0.64285
= 0.643
