<h3>The probability of picking a red face card from the deck is 
</h3><h3>The probability of NOT picking a red face card from the deck is 
</h3>
Step-by-step explanation:
The total number of cards in the deck = 52
The total number of red( Diamond + Hearts) face cards in the given deck
= 2 Red Queens + 2 Red jacks + 2 Red kings = 6 cards
Let E : Event of picking a red face card from the deck
Now , P( any event) =
So, here P(Picking a red face card) =
Hence, the probability of picking a red face card from the deck is
Now, as we know P (any event NOT A) = 1 - P(any event A)
So, P(NOT Picking a red face card) = 1 - P(Picking a red face card)
Hence, the probability of NOT picking a red face card from the deck is
Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle =
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB =
Length of BC =
Length of CA =
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;
Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.
