The half life of Meitnerium is 30 minutes. This means the amount of Meitnerium halves every
30 minutes. If H(t) - 9000(0.5)+30 describes
how much Meitnerium is left aftert minutes,
how much Meitnerium was there at the start?
(A word problem )

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
