Answer 2

Given :

ᴀ ᴄᴏɪɴ ɪs ᴛᴏssᴇᴅ 150 ᴛɪᴍᴇs ᴀɴᴅ ᴅᴀᴛᴀ ᴀʙᴏᴜᴛ ᴛʜᴇ ᴏᴜᴛᴄᴏᴍᴇs ɪs ᴀs ʙᴇʟᴏᴡ:

$\tiny\boxed{\begin{array}{cc} \: \sf Outcomes & \sf Frequency \\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{}& \\\sf H&\sf 90 \\\ \\ \sf T &\sf 60 &\sf \end{array}}$

To find :

ᴛʜᴇ ᴘʀᴏʙᴀʙɪʟɪᴛʏ ᴏꜰ ɢᴇᴛᴛɪɴɢ ᴀ ʜᴇᴀᴅ ɪɴ ᴀ ᴛʀɪᴀʟ

Solution :

Total number of outcomes =

• Number of times head came + Number of times tail came
• 90 + 60
• 150 outcomes

Times when head was the outcome = 90

Times when tail was the outcome = 60

Probability of getting a head

• $\sf\implies\:\dfrac{Favorable\:outcomes}{Total\:outcomes}$

• $\sf\implies\:\dfrac{90}{150}$

• $\sf\implies\:\dfrac{3}{5}$
