The events are independent events and probability of tossing a head and drawing a red marble is 1/7
a) The answer is present in the image attached below
b) Tossing of a coin and drawing of a marble are independent events as these two events do not interfere in the probability of each others events.
c) The probability of tossing a head and drawing a red marble is = =1/7 as we can see from the tree diagram that probability of tossing a coin and getting head is 1/2 and probability of drawing a red marble is 1/7. As they are independent events, their probability can be multiplied. Hence the probability of tossing a head and drawing a red marble is 1/7.
d) The probability of drawing two blue marbles if the first marble is not replaced and one at a time is 1/7. Probability of drawing first blue marble from the lot is 3/7 as favorable outcomes are 3 and total outcomes are 7. As the ball is not replaced the outcomes are changed. Now the number of blue balls are 2 and total number of balls are 6. So now the probability becomes 2/6. Hence the total probability becomes = 1/7

Answer:
50.000
Step-by-step explanation:
the formula to get ther is the following:
X + ( X * * 4 ) = 50.650
X is the initial amount of money you need to find
4 are the years of interests
So, If you have interests, it means that some money will be added to yours. But how much?
The problem says that every year 0.325% of your initial amount will be added, so you will calculate that amount( X * ) and you multiply it by four.
All this added to your initial amount will be the final number you have 50.560
Answer:
Who has that name?
Step-by-step explanation:
What's the question i'm really curious lol
You would distribute, 300 times 80 is 2400 and -3x times 1x is -3x so the equation would be y=2400-3x
Answer:
x is 3
