John is 31 and Jenny is 26
9 represents the event, 13 represents all possible events.
I have a bag of 13 marbles. 9 of my marbles are blue, 4 are red. My probability of reaching in and pulling out a blue marble at random is 9/13 (Which is 69%)
X/-9 ≥3 multiply both side by -9 to get rid of fraction
-9/1•x/-9 ≥-9•3
Cross cancel -9 on left side
x ≥ -27
The answer is :
24 ml oil
60 g onions
0.36 kg potatoes
0.4 l milk
All you have to do is divide everything by 4.
