Answer:
P(a pair with matching cards in different suits) = 1/52
Step-by-step explanation:
We are told that there are 4 suites and each suit has 13 different cards. This is a total of 52 cards.
Thus;
Probability of selecting one card of a particular suit = 13/52 = 1/4
If we now want to select a matching card of another suit without replacing the first one, then, we now have; 52 - 13 = 39 cards. Now, there are only 3 matching cards of the 3 remaining suits that is same as the first card drawn.
Thus; probability = 3/39 = 1/13
Thus;
P(a pair with matching cards in different suits) = 1/4 × 1/13
P(a pair with matching cards in different suits) = 1/52

Answer:
3
Step-by-step explanation:
The desired equation has 3 unknown coefficients. 3 independent equations are required in order to find those unknown values. The minimum number of data points required is 3.
1+4(6p-9)
1 + 4*6p - 4*9
1 + 24p - 36
24p + 1 - 36
24p - 351+4(6p-9)
1 + 4*6p - 4*9
1 + 24p - 36
24p + 1 - 36
24p - 35
Answer:
rational
Step-by-step explanation:
Any rational number can be expressed in the form
← where a and b are integers
Given
= - 2 or + 2
Since - 2 = and 2 = ← both in rational form, then
is rational
