Answer:
The probability of getting exactly 3 head=0.3125
Step-by-step explanation:
Given that probability of getting head p=0.5
So probability of getting tail q=0.5
Number of coin toss n=6
And number of trial r=3
We know that from Binomial distribution function,the probability given as follows
So now by putting the values
Now by solving this
The probability of getting exactly 3 head=0.3125
Answer:x =(5-√41)/2=-0.702 There is to both a r correct
x =(5+√41)/2= 5.702
Step-by-step explanation:I used your method and got 2 answers and they r both correct and anderstandable XD smart talk grosses me out lol
Because both angles are 90° and 90+90=180
Wait how would you even do this?
