Johnson Chemicals is considering two options for its supplier portfolio. Option 1 uses two local suppliers. Each has a "unique-e

sashaice [31]

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

$P_1=P_{se}+P_{ue}^2=0.015+(0.05)^2=0.015+0.0025=0.0175$

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

$P_2=P_{se}+P_{ue}^2=0.002+(0.13)^2=0.002+0.0169=0.0189$

Pue = probability of a unique event

Pse = probability of a superevent

Morgarella [4.7K]

When it says per month, it means to multiply. In this case, the expression would be;

25x+50

So however many months Fatima has spent at the gym, you would multiply that times 25 and add the initiation fee. Hope this helps.
