Adoctor can prescribe one of two drugs to treat a certain disease. drug a will cure 75% of the cases but has unwanted side effects in 40% of the cases. drug b will cure 50% of the cases and has unwanted side effects in 30% of cases. 60 patients are given drug a and 80 patients are given drug b. how many patients would you expect to experience unwanted side effects?

560

hope this : )

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
