Total number of balls in the bag = 6 + 3 + 7 = 16 balls

Probability of getting red ball = No. of favourable outcomes / Total

= 6/16 = 3/8

Probability of getting black ball ball = 7/16

Answer 2

HLO MATE HERE IS YOUR...

P=NO.OF FAVOURABLE OUTCOMES
______________________________

TOTAL NO. OF OUTCOMES

FAVOURABLE OUTCOMES =RED BALLS +BLACK
BALLS
=6+7
=13
TOTAL OUTCOMES =RED BALLS + BLUE BALLS + BLACK BALLS
=6+3+7
=16
NOW PUT THESE VALUES IN THE FORMULA WE GET

P=13
