Answer:
The probability of tails coming up is [tex]\dfrac{3}{5}[/tex]
D is correct
Step-by-step explanation:
Suppose a coin has been altered so that the probability of heads coming up is 2/5.
A coin has two possibility either head or coin.
We are given probability of heads coming up is 2/5
[tex]P(H)=\dfrac{2}{5}[/tex]
The sum of probability of all value is 1.
[tex]P(H)+P(T)=1[/tex]
[tex]\dfrac{2}{5}+P(T)=1[/tex]
[tex]P(T)=1-\dfrac{2}{5}[/tex]
[tex]P(T)=\dfrac{3}{5}[/tex]
Hence, The probability of tails coming up is [tex]\dfrac{3}{5}[/tex]
