I have quick question ; A company takes out an insurance policy to cover accidents that occur at its manufacturing plant.The probability that one or more accidents will occur during any given month is 0.6 . the number of accident that occur is independent of the nos. of accidents that occur in all other months.
Calculate the probability that there will be atleast four months in which no accidents occur before the fourth month in which atleast one accident occurs
And its Answer is 0.29 I am bit confused about the the four months thing,infact i am not clear with the question .Well ur replies are appreciated ,i am stuck in between.
