The time it will take Carley's dad to mow the lawn is 3.3 hours.

<h3>What is rate?</h3>

Rate is the ratio between two related quantities in different units. Therefore,

The rate Carley do the  lawn = 1 / 5

When they work together they do it the 1 / 2 rate.

Therefore,

let

the hours it takes Carley dad = x hours . Therefore,

1 / 5 + 1 / x  = 1 / 2

x + 5/ 5x = 1 / 2

cross multiply

2(x + 5) = 5x

2x + 10 = 5x

10 = 5x - 2x

10 = 3x

x = 10 / 3

x = 3.3 hours

Two cards are drawn, without replacement, from a standard 52-card deck. Find the probability of each of the following events: a)
aleksandrvk [35]

Answer:

Step-by-step explanation:

given that two cards are  drawn, without replacement, from a standard 52-card deck.

a) Both cards are red

Here there are 26 red cards and 52 total cards.  

Probability = \frac{26C2}{52C2} \\=\frac{26*25}{52*51} \\=\frac{25}{102}

b) Both cards are the same color

i.e. either both are red or both are black

Hence probability = twice of part a

= \frac{2*25}{102} \\=\frac{25}{51}

c) The second card is a queen, given that the first card is an ace.

If first card is an ace remaining are 51 cards with 4 queens\

So prob = 4/51
