Question

Tickets numbered 1 to 100 are placed in a box. Find the probability that a ticket selected at random has a number that is divisible by both 2 and 5

Answer 1

Step-by-step explanation:

50 tickets are numbered with even numbers so they are divisible by 2 in between 1 to 100

now we see the multiple of 5 which are odd

we will not see even because we have already counted them

so numbers divisible by 5 will be 5,15,25,35,45,55,65,75,85,95

total multiple of 5 are 10

all total number divisible by 2 and 5 = 50+10 =60

now applying formula we get,

60 / total number of tickets

= 60/100

= 6/10

= 3/5

so thats the prpbabilty pls click on heart button if u understand it....
