Answer:
0
Step-by-step explanation:
Given that:
The probability of event A = 0.4
i.e. P(A) = 0.4
The probability of event B = 0.5
P(B) = 0.5
Given that A and B are disjoint, then they do not have any elements in common. Thus, the probability that both events will occur is;
P(A ∩ B) = empty set {}, and the cardinality of the intersection of these two disjoint sets are, therefore, zero (0).
36 is the only logical answer

Answer:
30 grams
Step-by-step explanation:
So, first I had to figure out what 1 tin weight. Which was 350 grams because I divide 5 into 1750. Then I did 350+4 which gave me 1,400. I knew that there was three packets so 30 grams per packet should be the answer because 30×3 is 90 grams.
I think the answer is 121 cm^2
