Question

In each of 4 different competitions, jin has 60% chance of winning. Assuming that the competitions are independent of each other, what is the probability that: jin will win atleast 1 race

Answer 1

Answer:

1 - 0.4⁴

97.44%

Step-by-step explanation:

in has 60% chance of winning

=> probability of Winning = 0.6

probability of lossing = 1 - 0.6 = 0.4

probability that jin will win atleast 1 race

1 - Probability that he does not win any race

= 1 - 0.4⁴

= 0.9744

= 97.44%

Answer 2

Answer:

Try below its working fine for me.

Step-by-step explanation:

#n=4

#p=0.60

#k=1

from scipy import stats

probability=stats.binom.pmf(0,4,0.60)

actual_probability=1-probability

print(actual_probability)
