Two cards are drawn with replacement, one after the other, and the outcomes recorded. What is the probability that at least one
babymother [125]

Answer:

The probability is 0.231

Step-by-step explanation:

In this question, we are tasked with calculating the probability that out of two cards drawn with replacement from a pack of cards , at least one of the two is a face card.

In a standard pack of cards, there are 52 cards.

Now let’s calculate the number of face cards we have.

There are 12 face cards in a pack of cards. There are 4 of each of Jack, Queen or King

The probability of drawing a face card is 12/52 = 3/13

Now, we want to calculate the probability of at least one of the cards drawn are face cards.

Mathematically, what we are needing to calculate is

Probability of drawing a single face card or probability of the two being a face card

Now let’s calculate.

The probability of the first card drawn being a face card is 3/13. The probability of the second card not being a face card will be 1-3/13 = 10/13

The joint probability under this first set of condition will be 3/13 * 10/13 = 30/169

Now, for the second condition, here we are considering that both cards drawn are face cards. What we have is 3/13 * 3/13 = 9/169

Now in probabilities, whenever we are having the statement or, we add the probabilities together

Thus, the probability here would be 30/169 + 9/169 = 39/169 = 3/13

In decimal this will be 0.231

Tema [17]

Answer: 1.06^t.


Step-by-step explanation: We are given expression 1.06^t.

And 1.06^t expression is converted in (1.06^{1/2})^{2t}.

Now, we need to transform the expression into a single exponent expression using the properties of exponents.

We know, according to the properties of exponents

(a^m)^n = a^{m\times n}

Applying same rule in given expression, we get

(1.06^{1/2})^{2t} = (1.06)^{\frac{1}{2} \times 2t}

On simplifying exponents, we would get t in exponent.

=  1.06^t.
