110 members of a sports club play at least one of d games football, basketball nd volley ball. if 20 play football and basketball, 15 play football nd volleyball only, 26 play basketball and volleyball. x play all the three games, 2x each play one game, how many play basketball all together?

As Given ,

Members play football and basketball = 20

Members  play football and vallyboll = 15

Members play basketball and volleyball = 26

Members play all games = x

Members play only one game = 2x

There are total number of members  = 110

From above data we can write,

110 = 20 + 15 + 26 + x + 2x + 2x + 2x

110 = 61 + 7x

7x = 110 - 61

7x = 49

x = 7members

To find,

Member play basketboll altogether

= 20 + 26 + 2x + x

We know that x = 7,

= 20 + 26 + 14 + 7

=  67 members

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
