Sample Space

In the month of March 2019, Find the days on which the date is a multiple of 5. (see the given page of the calender)

There are 9 tickets in a box, each bearing one of the numbers from 1 to 9. 
One ticket is drawn at random from the box.  
Event A: Ticket shows an even number. 
Complete the following activity from the given information: 

Activity:

S = {__________}

n(S) = ____________

A = {________}

n(A) = ___________

Two coins are tossed simultaneously. The probability of getting at the most one head is ______.

A bag contains 3 white, 5 black and 2 red balls, all of the same shape and size. A ball is drawn from the bag without looking into it, find the probability that the ball drawn  

 not a black ball.

Two coins are tossed simultaneously. Complete the following activity of writing of the sample space (S) and expected outcomes of the events :
1) Event A : to get at least one head.
2) Event B : to get no head.
Activity : If two coins are tossed simultaneously
∴ s =  {${\displaystyle \square ,\text{HT},\text{TH},\square }$}
1) Event A : at least getting one head.
∴ A = {${\displaystyle \text{HH},\square ,\text{TH}}$}
2) Event B : to get no head.
∴ B = {${\displaystyle \square }$}

In a single throw of a dice, find the probability of getting 8.

When a dice is thrown, the number of sample points in the sample space are ______

If one coin is tossed, write the sample space ‘S’.
