The probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%. And the events are mutually exclusive.
<h3>What is the
addition rule of size for two subsets?</h3>
For two subsets A and B of the universal set U, we have:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
The probability of a new york teenager owning a skateboard is 0.37, of owning a bicycle is 0.36, and of owning both is 0.27.
Then the probability of the teenager owning a skateboard or a bicycle will be
P(A ∪ B) = 0.37 + 0.36 - 0.27
P(A ∪ B) = 0.73 - 0.27
P(A ∪ B) = 0.46
Thus, the probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%.
The events are mutually exclusive.

Answer:
Scientists think that foxgloves have evolved the poisons as an evolutionary adaptation and defense mechanism that provided them with better survival capacities.
As poisons are repellents which help the plants to repel any predator or attacker and enhance their survival. That is why scientists are of the view that old fox glove did not necessarily had this poison many hundred years ago but some how there would be facing harsh circumstances or alot of predators. Due to which, with the passage of time they developed these chemicals which enhanced their life time and survival chances.
Some poisonous chemicals from foxglove are:
- Deslanoside
- Digitoxin
- Digitalis glycoside
