Since the toss can either be heads or tails and only one of these can land at a time the answer is 13
350 / 7 = 50
50 * 2 = 100
100 new members
100 / 10 = 10
10 * 3 = 30
30 are new female members
Well, these are quite simple really, especially 1,2,3 and 4. If you read the questions carefully, you can understand it well. You don’t need to know the answer, you just need to understand
Firstly you can do 8 x 41 = 328.
Then 6 x 19 = 114,
114 + 328 = 442^2.
Hope this helps.
