Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.
Step-by-step explanation:
S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}
If AntiA reacts and AntiB reacts = AB (A∩B)
If AntiA does not react and AntiB does not react= O (A'∩B')
If AntiA reacts and AntiB does not react= A (A∩B')
If AntiA does not react and AntiB reacts= B (A'∩B)
Probabilities are used to determine the chances of events
The value of the probability P(x < 24) is 0.7895
<h3>How to calculate the probability P(x < 24)?</h3>This is calculated as:
So, we have:
Evaluate the sums
Evaluate the quotient
Hence, the value of the probability P(x < 24) is 0.7895

Answer:
Step-by-step explanation:
Sarah has $55
Her expenses are 3 shirts priced at $m each.
Total cost of 3 shirts at $m each would be the multiplication of each:
3 * m = 3m
The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:
Remaining Money = 55 - 3m
