Answer:
Answer will be
Step-by-step explanation:
We have given the expression
We have to simplify this expression with the help of property of exponent
According to property of exponent when there is exponent to exponenet then both the exponent are multiplied with each other
So
Here 4 and 3 are exponent to exponent so these are multiplied with each other
Answer:
Step-by-step explanation:
First we calculate the number of possible ways to select 2 cards an ace and a card of 10 points.
There are 4 ace in the deck
There are 16 cards of 10 points in the deck
To make this calculation we use the formula of combinations
Where n is the total number of letters and r are chosen from them
The number of ways to choose 1 As is:
The number of ways to choose a 10-point letter is:
Therefore, the number of ways to choose an Ace and a 10-point card is:
Now the number of ways to choose any 2 cards from a deck of 52 cards is:
Therefore, the probability of obtaining an "blackjack" is:
