Answer: x= 54
Step-by-step explanation:mathhhhh
I think it would be A but I'm not sure ._.
Step-by-step explanation:
(a)
ii.
21 - 5 = 16 play only chess.
iii.
23 - 5 = 18 play only cards
5 play both.
that is 16+18+5 = 39 that play at least one of these games.
i.
so, 45 - 39 = 6 don't play any of these games.
(b)
we have 16+18 = 34 pupils out of 45 that play exactly one game.
so the probabilty to pick one of them is as usual
desired cases / total cases = 34/45 =
= 0.755555555... ≈ 0.76
I say, just take a minute and remember why you are doing it. If you love it, just remember the love that you get from it. If you don't love it, then just think of it as getting experience for something else in life.
I get nervous before my cross country/track/half marathon races and all I think about is why I'm doing it in the first place.
Hope it helps!
