解析：
The probability that Claire does NOT pass chemistry is 1-0.75=0.25. The probability that she does NOT pass chemistry and she does pass history is then 0.25×0.88 =0.22.
The probability that Claire does NOT pass chemistry is 1-0.75=0.25. The probability that she does NOT pass chemistry and she does pass history is then 0.25×0.88 =0.22.
