Answer 1

Answer:

i) 3/10

ii) 2/5

iii) 3/10

iv) 7/10

v) 3/5 is the answer

Step-by-step explanation:

Total students = 50

playing cricket = 15

playing hockey = 20

playing volleyball =  50 - 35 = 15

i) plays cricket

P(E) = no. of favorable outcomes/ Total no. of outcomes

P(plays cricket) = 15/50 = 3/10  = 0.3

ii) plays hockey

sol. P(plays hockey) = 20/50  = 2/5

iii) plays volleyball

P(plays volleyball) =  15/50 = 3/10 = 0.3

iv) does not play cricket = 50 - 15 =  35

   P(does not play cricket) = 35/50  = 7/10  = 0.7

v) does not play hockey = 50 - 20 = 30

P(doses not play hockey) = 30/50

                                          = 3/5
