52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards
probability of getting 1 heart at first is 1/4
one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51
multiply
1/4 times 12/51=3/51=1/17

Answer:
Pranav had 36 posters on Monday.
Step-by-step explanation:
We can make up an equation to demonstrate this problem.
We don't know how many posters he had on Monday, so we can represent that amount as x. We know Pranav buys 10 more, so now it's x + 10. We also know that after he bought 10 more posters, half of all his posters got destroyed, leaving him with 23.
The final equation is:
(x + 10) ÷ 2 =23
We now need to isolate the x, so we multiply both sides by 2 to get rid of it.
It now equals:
x + 10 =46
Finally we subtract 10 from both sides.
Our answer is:
x =36
It would be 90m3 because all the angles are the same
