probability to solve at least one problem
= 1- probability to solve no problem
= 1-(1/5)⁴
=1-(1/625)
= 624/625
= 1- probability to solve no problem
= 1-(1/5)⁴
=1-(1/625)
= 624/625

Answer:
The probability that he solves at least one problem out of 4 problems is 369/625
Step-by-step explanation:
The probability that Alex will not solve a problem = 4/5.
The probability that Alex will not solve 10 problems = (4/5)4 = 256/625.
Hence, the probability that Alex will solve at least one problem
= 1 - 256/625 = 369/625.
