Question 1041727
p = 0.6 is the probability of landing heads


q = 1-p = 1-0.6 = 0.4 is the probability of landing tails


The probability of getting 4 tails in a row is q^4 = (0.4)^4 = 0.4*0.4*0.4*0.4 = 0.0256


Subtract this from 1:
1-0.0256 = 0.9744


The probability of getting at least one head is 0.9744




Final Answer: 0.9744
