Answer:
0.44
Step-by-step explanation:
given that the weather forecaster says that the probability of rain on Saturday is 20% and the probability of rain on Sunday is 30%.
It is common sense to know that Saturday and Sunday are independent of the other
Hence Probability that it rains on both days = 0.2*0.3=0.06
Since for independent events joint probability is the product of probabilities
required probability
= probability of rain over the weekend (Saturday or Sunday
= P(Sunday)+P(Saturday) -P(both)
=[tex]0.2+0.3-0.06\\=0.44[/tex]
