A coin is flipped 50 times and lands on heads 32 times. What is the experimental probability the coin will land on heads on the

next flip? (I think the answer is B. 50% because it doesn't matter how many times it was flipped before it's still a 50/50 chance.)
A. 32%

B. 50%

C. 56%

D. 64%

D because if you do a rate problem you do 50 times what equals 100 so times two then you do 32 times two

Answer:

50% B

Step-by-step explanation:

For a coin tossed once, the sample space is 2 i.e {H,T}.

If a coin is flipped once, the probability that it will land a head{H} is 1/2.

Since the possible outcome is 1 i.e the head and the total outcome is 2 which is the sample space.

Probability = Possible outcome of event/total outcome = 1/2 i.e 50%

Note that the number of times the coins has been initially flipped doesn't affect the probability of the next flip which will always be 1/2 for each flip since the coin can either land with a head or a tail.

Both tanji & kenji have same number of circles i.e. 50 .

<u>Step-by-step explanation:</u>

Here we have , tanji creates a "square, circle" repeating pattern. Kenji creates a "Square, circle, triangle, circle" repeating pattern. if both tanji and kenji have 100 shapes in their patterns,  . We need to find that which pattern contains more circles .Let's find out :

<u>tanji creates a "square, circle" </u>

it's given that tanji has 100 shapes and he is repeating this pattern . In this pattern circle comes 1 every time out of 2 shapes :

Total number of times circle = \frac{100}{2}(1)

Total number of times circle = 50

<u>Kenji creates a "Square, circle, triangle, circle" </u>

it's given that tanji has 100 shapes and he is repeating this pattern . In this pattern circle comes 2 every time out of 4 shapes :

Total number of times circle = \frac{100}{4}(2)

Total number of times circle = 50

Both tanji & kenji have same number of circles i.e. 50 .

there are 360 students in a school 162 of them are girls find the percent of girls find the percent of boys​
Ronch [10]

Answer:

Total number of students = 360

Total number of girls = 120

Total number of boys = x / ?

120/240= 1/2

50%

Step-by-step explanation: To find out the percent of the boys you first

subtract the whole amount of students which is 360 students in total to the number of girls (120) resulting 240. 240 in ratio is 1/2. 1/2 is 50%.

(Not sure, if this helps or not. I try my best to answer questions to make the asker to understand! Sorry, I tried. :c)
