Multiply both numerator and denominator by 2.
4*2 = 8 & 5*2 = 10
4/5 is thus equal to 8/10 or eight-tenths.
With a bar duagram, just divide/split it up evenly into 5 parts then colour in 4 of the pieces. Then, divide as a whole now make it so there's 10 parts - do this by splitting each 5 parts into 2 (put line through middle) to make 10 parts. Now you will see that there is 8 parts that are coloured in for 10 pieces compared to 4 coloured parts when there was 5 pieces.

Answer:
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
