Question

if the probability of winning the game is 0.7 then what is the probability of losing it

Answer 1

the probability of any thing is 1

since it is given that the probability of winning the game is 0.7
therefore , the probability of losing the game is 1-o.7=0.3

Answer 2

The probability of either losing or winning the game is 1 as any one thing must happen.
Probability of losing or winning the game=P(w)+P(l)
P(w)= probability of winning the game
P(l)= probability of losing the game.
P(w)=0.7
P(w)+P(l)=1
0.7+P(l)=1
P(l)=0.3
Hope you find this answer helpful.
