Answer:
There would be a 1/221 chance.
Step-by-step explanation:
So in a stack of cards, there are 52 total cards, 4 of which are 1's.
With this, you would have a 1/13 chance of picking up a card that's a 1 for the first picking, since 1/13 = 4/52.
Since this 1 card was picked and not put back by the second picking, the chance of picking up a card that is a one drops. With this, there is now a 3 / 51 chance that a 1 card is picked up since this card was removed.
Now with combining these two probabilities, multiply them together:
1/13 * 3/51 = 3/663 ---> 1/221.

Answer:
144 sweets
Step-by-step explanation:
Let
x----> number of sweets that Dan has
y----> number of sweets that Gordon has
z----> number of sweets that Malachy has
we know that
x=48
x/y=4/3----> y/x=3/4 ----> y=(3/4)x
Substitute the value of x
y=(3/4)48=36
x/z=4/5 ----> z/x=5/4 ----> z=(5/4)x
Substitute the value of x
z=(5/4)48=60
therefore
altogether there are x+y+z=48+36+60=144 sweets
