In a throw of 2 fair dice, there are 6*6=36 equiprobability outcomes.
To get a sum of 5, there are 4 ways, (1,4),(2,3),(3,2),(4,1) with probability of 4/36=1/9
To get at least one 5, there are 6+6-1=11 outcomes (note (5,5) has been counted in both, so subtracted from sum). The probability is 11/36
Since the two events are mutually exclusive (once we have a five, the sum can no longer be 5), we can add the probabilities to get the probability of one event or the other.
P(sum of 5 OR at least one 5)=1/9+11/36=4/36+11/36=15/36=5/9
Answer: 3/2 acre per day
Explanation:
8 1/4 = 33/4
5 1/2 = 11/2
Find the unit rate in acre per day:
(33/4) divide by (11/2)
33/4 x 2/11 = 3/2

Step-by-step explanation:
Given
Sharad bought a quintal of onion i.e. for
So, the cost price of onion is
He sells it at
Here, the Selling price is less than the cost price
So, he incurs a loss of
For a quintal it is
