Answer:
the second statement is true
Step-by-step explanation:
Answer:
=4/13
Step-by-step explanation:
There are 13 hearts in a deck
4 jacks
but 1 is the jack of hearts so we don't double count it
13+4-1 = 16
P( heart or a jack) = jack or heart/ total
= 16/52
=4/13
The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.
<h3>
About how many contestants will win?</h3>
The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).
Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5
Then, for a sample N, we can expect that about 0.5*N of the participants win.
In this case, the sample is 250, then we can expect that:
0.5*250 = 125
Around 125 of the contestants win the game

Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
