In a recent survey of 100 people, 52 indicated that they had flown on an airplane at least once, and 28 indicated that they had ridden on a train at least once. Only 10 of the respondents indicated that they had both flown on an airplane at least once and ridden on a train at least once. What is the probability that a person randomly selected from the sample indicated they had ridden on a train at least once but had never flown on an airplane

step-by-step explanation:

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

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
