Answer:
what does that mean
Step-by-step explanation:
Answer:
B would be a *dependent* event, and A would be an *independent* event.
Step-by-step explanation:
Independent events are separate events where the outcome in either event does not affect the other's probability. The opposite, where the outcome of the one event affects the other's probably, is dependent.
For Option A, taking a tile out and then replacing it does not affect the probability that the same tile will be picked for the 2nd picking.
For Option B, taking a tile out of the bag and then picking another tile are 2 separate events and both have different probabilities for picking identical tiles.
Therefore, Option B is dependent and Option A is independent.
Answer:
y= 3, (-5/4)
Step-by-step explanation:
4y^2-7y=15
4y^2 - 7y -15
(y-3)(4y+5)
A door alarm works in 72 out of 100 cases.
surveillance camera works in 68 out of 100 cases.
The probability that method A is used = 72/100
The probability that method B is used = 68/100
Since both method are used we find the probability of A and B
Probability ( A and B) = *
=
Answer:
B same form
Step-by-step explanation:
By using them for fractions or decimals. You can compare fractions by having them from least to greatest and it helps in getting the same denominator for fractions.
