Response:
Detailed explanation:
Probability for an event is calculated as the ratio of the size of the event space compared to that of the sample space.
The sample space encompasses all possible outcomes.
Event space represents the number of favorable outcomes for the event in question.
Thus
Let
x ------> size of event space
y ----- → size of sample space
so
Calculate the probability of the first student being left-handed
we have
substituting values
Simplify
Calculate the probability of the second student being left-handed
we have
substituting values
Calculate the probability that both selected students will be left-handed
Multiply the probabilities together.

Answer:Option C is correct.
C. The events are independent because the first ace was replaced before drawing the second ace.
Step-by-step explanation:
It is given that the probability of drawing two aces from a standard deck is 0.0059
If the first card is drawn and replaced, it alters the probability. Performing draws with replacement makes each event independent of one another
The chance of getting an ace on the first draw is 4/52, and with the replacement, the probability remains 4/52 for the second draw
Therefore, if we consider the first and second draws as event A and event B respectively, these events are independent
C. The events are independent because the first ace was replaced before drawing the second ace.
For a rectangle, the perimeter can be calculated as P=2l+2w. Assuming the length is horizontal and the width is vertical, the span between the x coordinates will give the length, while the span between the y coordinates will determine the width. Once these measurements are obtained, you can apply them to the perimeter formula. |7 -(-7)| = 14 gives l = 14, |5-(-2)| = 7 gives w=7. Therefore, P=2(14)+2(7), which results in P= 28+14, thus, P= 42.
