Answer:
0.25 or 25% or 1/4
Step-by-step explanation:
The probability that Javier volunteers for less than three events is the probability that he volunteers for exactly zero, one, or two events:
[tex]P(x<3) = P(x=0)+P(x=1)+P(x=2)\\P(x<3) = 0.05+0.10+0.10\\P(x<3) = 0.25 = 25\%[/tex]
Therefore, the probability that he volunteers for less than three events is 0.25 or 25%.
