Answer 1

Answer:

A bag contains 16 coloured balls. Six are

green, 7 are red and 3 are white. A ball is

chosen, without looking into the bag. Find the

probability that the ball chosen is :

(i) red

(ii) not red

(iii) white

(iv) not white

(v) green or red (vi) white or green

(vii) green or red or white.

Answer 2

Answer:

red = 7/16

take out the ans by dividing it will we either in mixed form or in decimal

not red= 6+3=9

=9/16 take out ans by dividing

white = 3/16 take out ans by dividing

not white= 6 + 7= 13

=13/16 take out the ans by dividing it will we either in mixed form or in decimal

always remember the formulae

No. of thing of what u want to take out probability divided by total no. of that thing

try the other ones plz I have no time
