Ответ:
Required probability is 0.3025.
Step-by-step explanation:
Given that probability of landing heads up in a toss of bent coin = 0.55
Then probability of getting head in 1st toss = 0.55
2nd toss is independent of the first toss.
Then probability of getting head in 2nd toss = 0.55
Hence probability of getting head in two tosses of the coin = (0.55)(0.55) =0.3025
Hence required probability is 0.3025.
Ответ:
0.3025
Step-by-step explanation:
Given:
The probability of landing heads P(h) = 0.55
The probability of landing heads when the coin is tossed again is 0.55 as both the events are independent and we are given the probability of heads P(h) = 0.55
So,
The probability of getting 2 heads in a row=0.55*0.55
=0.3025
