Answer:
Probability that A and We can solve
=80%X60%.
=80/100X60/100.
=0.8X0.6.
=0.48.
Probability that A can solve and We cannot solve
=0.8X(1-0.6).
=0.8X0.4.
=0.32.
Probability that We can solve and A cannot solve
=(1-0.8)X0.6.
=0.2X0.6.
=0.12.
Therefore, The Probability that at least one of them will solve
=0.48+0.32+0.12.
=0.92.
