Answer:
a) P=0.0175
b) P=0.0189
Step-by-step explanation:
For both options we have to take into account that not only the chance of a "superevent" will disable both suppliers.
The other situation that will disable both is that both suppliers have their "unique-event" at the same time.
As they are, by definition, two independent events, we can calculate the probability of having both events at the same time as the product of both individual probabilities.
a) Then, the probability that both suppliers will be disrupted using option 1 is

b) The probability that both suppliers will be disrupted using option 2:

Pue = probability of a unique event
Pse = probability of a superevent
Answer:
Number of cards given to sister = 35 card
Step-by-step explanation:
Find baseball card on Monday = 12
Find baseball card on Tuesday = 12 + 24 = 36
Remain baseball card = 13
Find:
Number of cards given to sister
Computation:
Number of cards given to sister = Find baseball card on Monday + Find baseball card on Tuesday - Remain baseball card
Number of cards given to sister = 12 + 36 - 13
Number of cards given to sister = 35 card
